rust-vst2

A library to help facilitate creating VST plugins in rust.

This library is a work in progress and as such does not yet implement all opcodes. It is enough to create basic VST plugins without an editor interface.

Please note: This api may be subject to rapid changes and the current state of this library is not final.

Library Documentation

TODO

• Implement all opcodes
• Proper editor support (possibly conrod + sdl2?)
• Write more tests
• Provide better examples

Usage

To create a plugin, simply create a type which implements plugin::Plugin and std::default::Default. Then call the macro plugin_main!, which will export the necessary functions and handle dealing with the rest of the API.

Example Plugin

A simple plugin that bears no functionality. The provided Cargo.toml has a crate-type directive which builds a dynamic library, usable by any VST host.

src/lib.rs

#[macro_use]
extern crate vst2;

use vst2::plugin::{Info, Plugin};

#[derive(Default)]
struct BasicPlugin;

impl Plugin for BasicPlugin {
    fn get_info(&self) -> Info {
        Info {
            name: "Basic Plugin".to_string(),
            unique_id: 1357, // Used by hosts to differentiate between plugins.

            ..Default::default()
        }
    }
}

plugin_main!(BasicPlugin); // Important!

Cargo.toml

[package]
name = "basic_vst"
version = "0.0.1"
authors = ["Author <[email protected]>"]

[dependencies]
vst2 = "0.0.1"

[lib]
name = "basicvst"
crate-type = ["dylib"]

Packaging on OS X

On OS X VST plugins are packaged inside of loadable bundles. To package your VST as a loadable bundle you may use the osx_vst_bundler.sh script this library provides. 

Example: 

./osx_vst_bundler.sh Plugin target/release/plugin.dylib
Creates a Plugin.vst bundle
